Three Camomiles
Chamomile is the name given to the group of plants which belong to the family Asteraceae. Chamomile flowers are known for the aromatic and bitter taste. German chamomile (Matricaria recutita) and Roman chamomile (Chamaemelum nobile) are the two major types of chamomile used as herbal medicines. Chamomile tea is known for its medicinal properties and it is used as a tonic, anodyne, antispasmodic, anti-inflammatory, antibacterial, anti allergenic, and as a sedative.
Side Effects
Chamomile is generally considered safe and nontoxic. But as Chamomile is used to treat a wide range of conditions and diseases, both internally and externally, we cannot overlook chamomile tea side effects.
  • According to the researches, Chamomile may increase the risk of bleeding or enhance the effects of warfarin therapy (anticoagulant therapy used to control and prevent thromboembolic disorders).
